heads up: Lua changes

The Lua in pkgsrc has been rearranged: there are now two Lua packages
(lua51 and lua52) and multiversion support for Lua modules, so the
names of Lua module packages all just changed.
Unfortunately you can't (yet) have lua51 and lua52 installed together;
that will take further work.
The default is lua52, but you can now change this by setting
LUA_VERSION_DEFAULT=51.
I have not yet found or marked all the packages that don't work with
Lua 5.2; that should get done fairly quickly, but in the meantime post
or send-pr if you run into ones that haven't been marked.
